i was done same thing in WPF by using the below code:
Environment.GetFolderPath(Environment.SpecialFolder.Desktop);
But in WinRT Environment doest not have reference GetFolderPath.How could i achive same thing in WinRT.
Thanks
you can use the blow sample code
StorageFolder testFolder = await StorageFolder.GetFolderFromPathAsync(
Environment.GetFolderPath(Environment.SpecialFolder.Desktop)
);
also there is more information about special folders in msdn
Windows Runtime apps don't have access to arbitrary locations in the file system. They can directly access their own data and can get access to well KnownFolders such as the Pictures and Music libraries.
They don't have access to the desktop unless the user has granted it explicitly via a file or folder picker.

Is it possible to retrieve the computer name when developing a Chrome Extension, for example "Jenny-PC"?
At first glance I did not find the API, but maybe I missed something.
If you are quite the daredevil, you could try to extract that info from a NPAPI plugin. This is quite dangerous, as you can read more about on the chrome extension site
No directly, for security reasons extensions can't access OS services.
But, hacker way, you may find some odd way to get what you're looking for.
If your extension has file:// permission, it can read system configuration files.
If you can get the user drop some file containing the name you want on some receiver in your extension's page, you can read it with HTML5 FileReader object.
If you can get the user download and execute some script you wrote (for example a .bat in Windows), it can grab that name and send to the extensions in various ways:
- writing it in a file the extension can read
- executing something like
"c:\chrome install folder\chrome.exe" chrome://extensions/yourextensionkey/receiver.html?name=thenameyourellokingfor
About file:// permission
Chrome Web Store doesn't allow uploading nor publishing extensions with such permission. But the extension works if you install it as a developer, or as .crx .
I'm not sure, but I think you can upload it to Chrome web store modifying it, in order to ask for permission.
I am thinking about having the following use-case:
User installs application on local machine.
User goes to our website, and are presented with many links (choices).
User clicks on a link.
Application starts, with some information contained within the link passed to the application.
Step 4 is obviously a security minefield. The end goal is that the user makes a choice, and if the application is installed, it starts with some information passed to it (ie command line parameters, or perhaps a temp file somewhere on the user's machine)
Can I/ Should I access the registry from javascript? Are there any ideas about how I might go about this? Do you have an alternative suggestion?
Assuming the applications the user installs are also developed by you.
Register a file extension for use by the specific application - then your web links can be links to a file that is downloaded and auto-run by your app. The file could contain details on the defaults for your app to use.
Sort of like how clicking on a .pdf file opens your pdf reader.
As an alternative to the file-extension solution you may want to know about Custom Application Protocol feature. Link is for Windows but there are nearly same techniques on other systems. I can't say if this approach works in every browser but you may want to try it out.
Accessing the registry from JavaScript inside a browser is nigh on impossible for the security implications. To access the registry from the web, I'd imagine you'd have to use a binary (C++ or others) program that can read the registry, but also has an HTTP module to communicate with your server.
Sounds like you might need the Click Once deployement feature for your app. I think once it's installed over http there should be a pretty easy way to launch an executable.

We've got an intranet which normally serves all info/documents that appl to the whiole company (employee handbooks, minutes, etc...)
Most of these work by having the web server parse a folder and present the files to the user.
The problem in this case is that the latest folder is restricted to cerain users. As Kerberos is not currently an option, I was planning to side-step the issue and just insert a link which opens up a UNC path:
file://\Server\SecureFolder\
I've just found out that since XPSP2 this hasn't been possible with standard HTML/JS.
Does anyone know of a nother way this can be done? It's internal so I've got a lot of control over the webserver (but domain config changes will have to be justified)
I'm wondering if there's something like .Net or an ActiveX [shudder] solution or similar?
Thanks in advance for any help.
Seems the solution was to do it without Javascript and without the file://
The following works:

I am having this peculiar problem in hand. I have newly developed J2Me App Midlet, now I want to give this App to the user as a download from my website. I want to build the application programmatically as user clicks the link to download it, It is so because there is a set variable data, I want to hard code inside J2Me App, depending upon the user profile. I can not make sets of J2Me App ready to download as this would be too huge a task.
Can any one tell me how this can be achieved ?
The website is ASP based website.
Instead of hardcoding the data in the class file, why don't you use a jad file property and just generate the JAD File Property while the user download the application. Inside the MIDlet you can just refer to the property using MIDlet.getAppProperty() method to read that JAD property.
Hope this helps
We're using the Mantis bugtracker (version 1.1.8), which is based on PHP. To ease the workflow of adding bugs we'd like to add an option to paste screenshots from the clipboard directly into the 'new bug form'.
Screenshots make bugreports much more valuable for developers, so I'd like to make adding them as easy as possible. Preferably without using an external application, but right in the browser.
I've looked all over for a way to add this, but no luck. How do other people do this? Am I missing something obvious?
edit: The bugtracker is a private one, in a small company, so I'd be willing to accept the security risks that for example Java applets present.
There isn't really a way to do this short of using ActiveX, applet or Flash-type technology on the client. Even then, there are numerous security roadblocks. A browser has no easy way to convert stuff from the clipboard into a suitable format for upload to a website, and even if it did there would be security concerns. For example, malicious code in a page could copy sensitive information from your clipboard and send it to the page's site without you even knowing it was happening.
Update: There is a standalone screen capture utility which claims to work with Mantis (and a whole bunch of other bug-trackers). This is probably your best option.
There is a drag n drop image attacher Java applet for Atlassian Confluence which has the functionality you need. It only supports Confluence but as the sourcecode is freely available under BSD you should be able to customize it to your needs.
Forgot the link:
http://confluence.atlassian.com/display/CONFEXT/Drag+and+Drop+Image+Attacher+Plugin
I've managed to build my own solution that works quite well. It places a Java file upload applet on the pages where you'd want to attach a screenshot. The applet has two buttons:
'paste screenshot', which pastes an image from the clipboard into the applet
'upload screenshot', which uploads the pasted image to the /tmp dir on the Mantis server and uses a javascript callback to place the autogenerated filename of the uploaded image into a form field.
Once the form is submitted, a new function in Mantis uses the filename in the form field to move the image from /tmp to the final location and processes the image just like other attachments. If the form is never submitted the uploaded file remains in /tmp and will eventually be purged by the server.
It works well, but has one drawback that I cannot avoid: I'm using Java to get access to the client's clipboard, but that requires breaking the JVM sandbox. Apparently, this can be done if you digitally sign the applet, which requires a rather expensive yearly payment (something like $500) to a company like Verisign (currently free options like cacert.org are still limited in their usefulness).
Another way to allow Java applets access to the clipboard is to create a file called .java.policy in your home or profile directory. This file should contain the following (Replace the domain with the domain that hosts your Java applet):
grant codeBase "http://bugs.example.com/-" {
permission java.awt.AWTPermission "accessClipboard";
};
Thankfully the solution is cross-browser compatible since the JVM always checks the same file regardless of the browser used. Since my solution requires having this .java.policy file on each client computer I don't consider it ideal, but workable in a controlled company environment.
I looked in to this also. No real easy way, so instead I allowed them to upload an unlimited number of files and those files would then be "attached" to that bug. It actually turned out to be better because they can upload screenshot, spreadsheets, word docs, etc.
Like yours, this is an internal only site so security is light. I did this in ASP.Net, but the general idea is that when they are looking at a page for a bug they have an upload box. When they upload something I pre-append it with the bug id. So ScreenShot.jpg becomes 233_ScreenShot.jpg.
Also on that page is a grid (GridView) that is bound to all of the filenames in my upload directory that start with that bug id.

For tech-oriented users, there's always to possibility of using Eclipse + Mylyn + Mylyn-Mantis connector.
Then uploading screeshots is very easy:
